  7. 4Revision History

2.2.1 Processor

The AM5748 processor is the central processing unit for this IDK EVM. The interface circuitry, memory ICs, and connectors implemented on the board around the AM5748 processor provide development support for the many industrial communication interfaces available on this platform. See the AM574x Sitara Processors Silicon Revision 1.0 Data Manual (SPRS982) and the AM574x Technical Reference Manual (SPRUIH8) for details about the processor.

The AM574x IDK EVM contains system configuration for the boot mode control inputs SYSBOOT[15..0]. These can be strapped using resistors. The default configuration will meet the needs of most developers. Resistor reconfiguration is supported so that you can explore other boot configurations of the AM574x processor. See Section 2.4 for more details.
